Clinico-Pathological Significance of Tumor Infiltrating Immune Cells in Oral Squamous Cell Carcinoma-Hope or Hype?
Head Neck
January 2025
Department of Pathology, All India Institute of Medical Sciences, Rishikesh, India.
Background: To correlate between immunohistochemical expression of tumor-infiltrating lymphocytes (TILs), tumor-associated macrophages (TAMs), and natural killer (NK) cells with the AJCC 8th edition TNM staging system and other disease-modifying clinico-pathological variables.
Methods: The representative histology sections of tumor invasive margin (IM) and tumor core (TC) were selected according to the International Immuno-Oncology Biomarker Working Group and were subjected to immunohistochemistry with antibodies for TILs (CD3, CD8, FOXP3), NK Cells (CD57), TAMs (CD68, CD163) and pan-leukocyte marker (CD45). Histo-immuno-density-intensity (HIDI) scoring was calculated as a product of the proportion and intensity of staining.
Real-World Impact of Olaparib Exposure in Advanced Pancreatic Cancer Patients Harboring Germline BRCA1-2 Pathogenic Variants.
Cancer Med
February 2025
Department of Medical Oncology, IRCCS Ospedale San Raffaele, Milan, Italy.
Introduction: Pancreatic cancer arising in the context of BRCA predisposition may benefit from poly(ADP-ribose) polymerase inhibitors. We analyzed real-world data on the impact of olaparib on survival in metastatic pancreatic cancer patients harboring germline BRCA mutations in Italy, where olaparib is not reimbursed for this indication.
Methods: Clinico/pathological data of pancreatic cancer patients with documented BRCA1-2 germline pathogenic variants who had received first-line chemotherapy for metastatic disease were collected from 23 Italian oncology departments and the impact of olaparib exposure on overall survival (OS) was analyzed.
Association of blood group types and clinico-pathological features of gynecological cancers (GCs).
BMC Cancer
January 2025
Molecular Diseases & Diagnostics Division, Infinity Biochemistry, Infinity Solutions Unlimited, Sajjad Abad, Chattabal, Srinagar, 190010, Kashmir, India.
Background: Gynecological cancers (GCs) affect the reproductive system of females, and are of multiple types depending on the affected organ most common of which are cervical, endometrial, ovarian cancers. Among different risk factors for GCs, ABO blood group system is considered as one of the pivotal contributing factors for increased susceptibility of GCs. The aim of our study was to report on the demographics of GC patients and to investigate the relationship between the ABO blood group system and the risk of acquiring GC in our population.
View Article and Find Full Text PDFIntroduction: Indoleamine-2,3-dioxygenase (IDO) converts L-tryptophan (T) to L-kynurenine (K) resulting in an immunosuppressive microenvironment. Aim of the current study is to evaluate in patients with neuroendocrine tumor (NET): 1) T and K concentrations; 2) correlation with clinical outcome; 3) relationship between IDO activity and inflammatory cytokines.
Methods: A cross-sectional study was performed to investigate the IDO pathway in patients in follow-up for NET.

Gemelli IRCCS, Rome, Italy; Department of Life Sciences and Public Health, Catholic University of Sacred Heart, Rome, Italy.
Objectives: This study aimed to define the frequency of positivity of several immunohistochemical markers in uterine tumor resembling ovarian sex cord tumor (UTROSCT).
Methods: All consecutive UTROSCT cases were retrieved from consultation files of one of the authors. Histological and immunohistochemical slides were reviewed.
